Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the battery if working on electronic components.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts with a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
- Remove the caliper by unfastening the caliper bolts using a socket wrench.
- Carefully slide the caliper off the rotor and support it using a bungee cord to avoid straining the brake line.
- Remove the old brake pads from the caliper bracket.
- Inspect the brake pad thickness; if less than 3 mm, replace them.
- Install new brake pads in the caliper bracket, ensuring they are seated correctly.
Tools Required: Socket set, torque wrench, bungee cord.
Safety Warnings: Avoid letting the caliper hang by the brake line to prevent damage.

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
- Check the rotor for scoring or warping; if damaged, remove the rotor by unbolting it from the hub.
- Clean the hub surface to ensure proper seating of the new rotor.
- Install the new rotor, securing it with the appropriate bolts to the manufacturer’s torque specifications.
Tools Required: Socket set, torque wrench.
Safety Warnings: Ensure to wear gloves and safety glasses during rotor replacement.

5. Reassemble and Test

Reattach the caliper over the new pads and secure it with the caliper bolts.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications.
Reconnect the battery if it was disconnected.
